Two sides to every coin. "That" ADC main.
Heads.
ADC: "Gee, bot lane sure is pushed up. I'm gonna go clear that"
ADC's team: "Boy this sure seems like a good idea to randomly engage while we're aware that we're down a teammate"
Teamfight goes horribly.
ADC's team: "WTF? Why didn't you come to help us?"
Tails.
ADC's team: "We need you to group with us. They're taking out inhibitor towers!"
ADC: "But I need to keep slowly farming this wave that isn't pressuring a tower to catch back up and get back into the game."
Team gets initiated on and the enemy sets up their victory.
ADC: "GG shit team couldn't even defend"
It's usually one or the other.
